We’ve all seen (or been) those passengers running through the airport, suitcase flying behind them, as they desperately try to make their connecting flight. Now, Delta Airlines has come up with a solution to get connecting passengers to their aircraft as quickly as possible — whiz them there in a Porsche.

Passengers that are running late for their next flight have been surprised to find themselves shuttled across the tarmac in a $50,000 luxury sports vehicle. Delta says Porsche donated eight of the cars as part of a marketing campaign, and the perk helps to keep fliers happy.But don’t get too excited yet — the service is only available to super elite frequent fliers, and even then, you have to be running really late for your flight. Although that’s just a small percentage of all air passengers, those frequent fliers who travel more than 125,000 miles per year are where the airlines make a lot of their money, so ensuring those customers are satisfied is good for business.

The Porsche rides program is currently available in Atlanta, but is being expanded to New York, Minneapolis and Los Angeles this month.

It has been half a century since the historic March on Washington, when the nation’s citizens converged on the capital calling for civil and economic rights for African Americans. To mark the 50th anniversary, we rounded up several great destinations where you can retrace the steps of the Civil Rights Movement.

Montgomery, Alabama. This city is packed with significance and there are a number of civil rights sights for history buffs to absorb. You can see the bus stop where Rosa Parks famously refused to give up her seat, visit the Freedom Rides Museum housed on the site of an early confrontation and witness the site of the 1965 Voting Rights March, to name but a few options.National Civil Rights Museum, Memphis, Tennessee. This museum, which traces the history of the Civil Rights Movement, is housed in a complex of buildings including the Lorraine Hotel where Dr. Martin Luther King Jr. was assassinated in 1968. You can even visit King’s room — 306 — which has been recreated to look exactly like it did on that fateful day.

Selma, Alabama. Visitors to this town can see the site of the Selma to Montgomery marches, including the 1965 protest that ended in a bloody clash with police on the Edmund Pettus Bridge. Don’t miss the National Voting Rights Museum, which recounts the story of the marches and the campaign to end voting-related discrimination.

Martin Luther King Jr. National Historic Site, Atlanta, Georgia. This historic site recalls the life of the civil rights leader, including the home in which he grew up, a museum, the church where his father preached and his tomb.

What do you do on layovers? Nap? Catch up on email? Mindlessly watch some sports without any rooting interest? Christopher Berger, a physiologist, has a better idea.

It’s simple. Stand up. Walk away from the gate. Heck, leave the premises if you have at least three or four hours. There’s no rule that says you have to spend the layover inside the airport. Baltimore has a fitness trail encircling the airport grounds (and it’s not the only one with a walking path). So what if it’s not the most scenic stroll of your life? “Anything is better than eating fast food and waiting for your flight to show,” Berger says.

Berger, chair of the American College of Sports Medicine’s Task Force on Healthy Air Travel, is on a mission against the sedentary airport lifestyle. He understands that people on vacation might want to chill; he’s not above vegging out in a gate area from time to time himself. But for frequent business travelers with a fitness regimen at home, falling out of the routine quickly takes a toll. “If you travel a lot, this is a big deal,” he says. “You can’t let yourself be that deconditioned. You have to have a plan if you travel at least once a week. It’s worth talking about.”A plan is as easy as packing a pair of lightweight walking shoes and taking a brisk stroll around the airport. Check out the public art, the chapel, the yoga room or services you might not expect to find, like medical clinics offering immunizations and air-sickness medicine. You might not need to see a doctor, but it’s interesting to explore.

Since 2007, Berger has done much of this himself conducting a study of fitness opportunities at every major U.S. hub airport. He has flown 488 times, including 100 cross-country trips. The research is complete, and he expects to release the findings this summer – and eventually convince airports to make it easier to burn calories on a layover without sprinting to catch a connecting flight.

The return of airport lockers would go a long way toward freeing travelers from the gate area. “Airports needs to be willing for you to drop off your bag.” he says. “But post-September 11, people don’t like unattended bags at airports.” And in the wake of the Boston bombings, Berger’s not expecting an attitude shift anytime soon. In the meantime, he recommends checking to see if your airline loyalty program babysits luggage.

If you can check bags and carry on just a backpack, you can become as mobile as Berger is on layovers. Unlike most travelers, he’s not paranoid about leaving the terminal if he has at least three hours (and he has never missed a flight when doing so), especially in cities with an airport light rail station. In Salt Lake City, you can get in a round of golf at a course adjacent to the airport.

Minneapolis’s airport is a favorite for a layover field trip. “Out of the airplane, you can be at the light rail in under 15 minutes, and that runs every 10 to 15 minutes. I’d say within 45 minutes you can be downtown. It’s totally walkable, flat, well laid out, pedestrian paths all over the place,” he says. “There are parks you can go to. Just lay in the sun, get some fresh air. Budget 45 minutes or so to get back. I’ve done it in three hours.”

He has a trick for a speedy return: Use the terminal likely to have the shortest TSA security line. Forget about the terminal with the airline that has a hub there. For instance, in Atlanta, don’t go through Delta’s terminal. Return through the one serving US Airways and Air Tran. “You can bet dollars to donuts that line won’t be as long,” Berger says.However, do your homework to make sure you can walk from your entry terminal to your gate. At Washington National, for instance, changing terminals can require a bus ride, negating the time savings.

Berger hopes airports will move in this direction for the sake of competition, if nothing else. And he believes the strategy is best suited for big airports in the middle of the country. “In West Coast or East Coast cities, no one changes planes except for international flights,” he says. “It doesn’t work as conceptually as it does at a place like Dallas or Denver or Atlanta.”

Don’t overlook full-service hotels near airports for fitness amenities, too, especially if it’s raining and you can’t go outside. Many offer day passes to their gym and swimming pool, Berger says, and are easily accessible by light rail or shuttle from the airport.

Simply bypassing the tram between terminals and walking – which isn’t always as far as you might imagine – marks baby steps toward breaking the habit of layover laziness.

“It’s not going to turn you into a marathon runner,” Berger says. “But you’re expending something in the way of calories.”

Much ado about pork products is made on Gadling, with good reason. Even if you’re sick to death of pork-centric eateries, and lardo this and sausage that, it’s hard to deny the allure of the other white meat (I can’t tell you how many vegetarians and vegans I know who still have a jones for bacon).

For those of you wanting to attend the ultimate porkapalooza, get your tickets for Cochon 555, a traveling, “National Culinary Competition & Tasting Event Dedicated to Heritage Pigs, Family Wineries & Sustainable Farming.”

The 10-city tour kicks off February 17 in Atlanta, and will include stops in New York; Boston; Chicago; Washington, DC; Miami; Vail; Seattle; San Francisco; and Los Angeles, before culminating in the dramatic Grand Cochon at the FOOD & WINE Classic in Aspen on June 16. Notice that Colorado gets two Cochon visits? The South isn’t the only place that appreciates pork.

Cochon was created by Taste Network’s Brady Lowe to raise awareness about, and encourage the sustainable farming of heritage-breed pigs. At each destination, five celebrated local chefs must prepare a nose-to-tail menu using one, 200-pound, family-raised heritage breed of pig. Twenty judges and 400 guests help decide the winning chef. The 10 finalists will then compete at the Grand Cochon for the ultimate title of “King or Queen of Porc.”

As a native Californian, few things get on my nerves more than hearing the abbreviation, “Cali.” I don’t know why it irritates me so much, but I suspect it’s the knowing, insider-y tone that usually accompanies it. “Yeah, man, I just got back from a trip to Cali. It was hella cool.”

Aaargh. Also right up there is “Frisco.” Let me just tell you that Californians do not, ever, under any circumstances, refer to their state as “Cali,” nor “The City” as “Frisco.” San Francisco even famously had a laundromat called, “Don’t Call it Frisco.” I also dislike “Berzerkley,” “San Berdoo (San Bernadino)” and “The States (anyone in Hawaii referring to the Mainland).”

With these grating abbreviations in mind, I asked my Gadling colleagues what city nicknames bug them. The response was fast, furious and lengthy. Below, some highlights:

Libby Zay: I personally hate “Hotlanta.” It’s also pretty annoying when people add “tucky” or “neck” as suffixes. As in, Fredneck, Maryland, or Brunstucky, instead of Brunswick, Ohio … I suppose Pennslytucky would be more of a geographic region.”

Author admission: Guilty as charged, Libby.

Kyle Ellison: “Lost Wages,” for Las Vegas, and “N’awlins” for New Orleans.

Elizabeth, I promise to never refer to my hometown of Thousand Oaks as “Thousand Jokes” again.

McLean Robbins:“Naptown” for Annapolis and “The District” from anyone not a local to Washington, DC.

Meg Nesterov:Calling cities the Paris/Venice/X/ of the North/East, et al.

Sean McLachlan, resident history buff: Missouri is often called “Misery,” generally by outsiders from northern states and occasionally by frustrated Missourians. The term actually has old roots. The 18th century French settlers in Ste. Genevieve found the place so boggy and full of mosquitoes that they nicknamed it misère.
